A novel method for nucleic acid sequence determination.
A novel sequencing methodology which should be readily and completely automated and based on fragmentation of a nucleotide or deoxynucleotide sequence into short fragments, and subsequent quantitation of the fragments by hybridization to oligo-deoxyn nucleotides on a solid support.
Photochemistry in Terrestrial Exoplanet Atmospheres I: Photochemistry Model and Benchmark Cases
We present a comprehensive photochemistry model for exploration of the chemical composition of terrestrial exoplanet atmospheres. The photochemistry model is designed from the ground up to have the…

It is argued that it is the nature of the liquid in which life evolves that defines the most appropriate chemistry, and Fluids other than water could be abundant on a cosmic scale and could be an environment in which non-terrestrial biochemistry could evolve.
PHOTOCHEMISTRY IN TERRESTRIAL EXOPLANET ATMOSPHERES. II. H2S AND SO2 PHOTOCHEMISTRY IN ANOXIC ATMOSPHERES
Sulfur gases are common components in the volcanic and biological emission on Earth, and are expected to be important input gases for atmospheres on terrestrial exoplanets. We study the atmospheric…
Phosphine gas in the cloud decks of Venus
Measurements of trace gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbour, Venus, has cloud decks that are temperate but hyperacidic.…
An astrophysical view of Earth-based metabolic biosignature gases.
Key points of Earth-based microbial metabolism that are useful to the astrophysical search for biosignature gases on exoplanets are reviewed, including a list of primary and secondary metabolism gas byproducts.
BIOSIGNATURE GASES IN H2-DOMINATED ATMOSPHERES ON ROCKY EXOPLANETS
Super-Earth exoplanets are being discovered with increasing frequency and some will be able to retain stable H2-dominated atmospheres. We study biosignature gases on exoplanets with thin H2…
A BIOMASS-BASED MODEL TO ESTIMATE THE PLAUSIBILITY OF EXOPLANET BIOSIGNATURE GASES
Biosignature gas detection is one of the ultimate future goals for exoplanet atmosphere studies. We have created a framework for linking biosignature gas detectability to biomass estimates, including…

In all cases, consulting is the most economically rewarding option, and for the ‘average’ academic, being involved in a venture-funded start-up is the worst.
Exoplanet Biosignatures: Future Directions
A Bayesian method for guiding future directions for detection of life on exoplanets is introduced and examples for how the Bayesian formalism could guide future search strategies are provided.
